This wider view of Snowdon is across the Gwynant valley near Gwastadannas on the Beddgelert road . Cwm Dyli hydroelectric power station lies in the bottom of the valley It was built by the North Wales Power and Traction Company in 1905. A small dam was built at the terminal moraine across Llyn Llydaw (at 1400 ft) and piped to the power station in the bottom of the valley over 1000 ft below. The catchment area for rainwater and melted snow is over 4 sq. kilometres. It is one of the oldest power stations running in the UK today, and still generating electricity for the National Grid. It precedes both the Snowdon National Nature Reserve and the National Park. Originally with 2 turbines and generators supplied by 2 water pipes it now operates a single generator, powered by a Francis turbine, using 1 larger diameter pipe. At full output the station produces 10 MW of electricity and uses 3,500 litres of water per second. The water flows out into the Afon Glaslyn, that feeds Llyn Gwynant seen in the photograph looking southwest down the valley, thence to Llyn Dinas and on to Beddgelert .
